## Overview

The Payment Plugins for PayPal WooCommerce WordPress plugin before 2.0.26 does not validate the order key before adding order data to the JavaScript configuration it outputs on the front end, allowing unauthenticated users to obtain the secret that gates access to any order and, through it, that customer's billing and shipping details, by iterating sequential order identifiers.
